Embodiment Construction
[0023]Referring to FIG. 1 of the drawings, a power adapter according to a preferred embodiment of the present invention is illustrated, wherein the power adapter comprises an insulating casing 10 which comprises an enclosing wall 11 and defines a sealing chamber 12 therein and a power transforming unit 20 disposed in the sealing chamber 12 for converting an input power into an output power.
[0024]The power adapter further comprises a heat sink device 30 which comprises a heat dispersing member 31 supported within the sealing chamber 12 at a position between the enclosing wall 11 and the power transforming unit 20 to thermal-communicate with the power transforming unit 20, wherein the heat dispersing member 31 has an air insulating cavity 310 formed above the power transforming unit 20 in such a manner that when the power transforming unit 20 generates heat for heating up air within the air insulating cavity 310, the heat is diffused throughout the air insulating cavity 310 so as to e...
